Either when we get notice that the PR is closed, this time I need to
create one. But we have similar issues where we already have PR's.
Or we check when a new gcc release come out, if the results from
"grep bfin package/*/*mk" are still required.

I think better then never ending autobuild failures.

best regards
 Waldemar
